Is it true that air conditioners don't cost electricity?
She stated that Gree is developing a new technology that combines solar energy, energy storage, and air conditioning. The air conditioner becomes a power plant, eliminating the need for city power grids or long-distance transmission. It gathers sufficient energy to generate electricity through the air conditioner, storing excess power while ensuring cooling or heating. This would allow for electricity-free lighting at night. If this technology is fully implemented globally, global temperatures could drop by half a degree Celsius.
What exactly is the "self-powered" technology described by Dong Mingzhu? Today, an official article revealed Gree's "photovoltaic air conditioner that doesn't require electricity bills."
It is understood that Gree's photovoltaic direct-drive variable frequency centrifugal chiller system is the world's first large-scale central HVAC system with photovoltaic power generation function. It is a new type of integrated power generation and consumption system and the best application model of the national distributed energy policy. It provides a green building support solution that integrates power generation and consumption, including energy-saving equipment, clean energy and intelligent management.
In 2013, Gree pioneered the "central air conditioning without electricity bills"—the photovoltaic direct-drive inverter centrifugal chiller. After evaluation by an authoritative expert group, it was deemed a "global first" and reached an "internationally leading" level. This achieved energy self-sufficiency for central air conditioning, eliminating the need for electricity bills and ushering in a zero-energy era for central air conditioning.
Gree's photovoltaic direct-drive inverter air conditioning system not only saves energy but also stores energy. This system creatively integrates renewable energy with air conditioning technology, operating in five modes: pure photovoltaic power generation, pure air conditioning, photovoltaic power generation and system power generation, photovoltaic power generation and system power consumption, and photovoltaic air conditioning. These five modes can be switched instantaneously. It not only achieves zero electricity costs but also generates electricity externally, reducing grid pressure and achieving energy self-sufficiency.
Photovoltaic direct-drive inverter air conditioning systems can create a living and working environment with "zero electricity bills," "zero worries," and "zero waste." Related data shows that if 10% of the world's air conditioners used Gree photovoltaic air conditioning systems, CO2 emissions could be reduced by 1.312 billion tons annually.
Today, Gree solar air conditioners have a presence in 25 countries and regions around the world. In addition to China, Gree solar air conditioners can be found in the Middle East, North America, Southeast Asia, South America, Europe and other regions, serving thousands of major projects at home and abroad.
